Tīmeklis2024. gada 21. aug. · In this case, the effective Lamb-Dicke parameter allows for the necessary coupling between qubit states and motional states . Gates with dressed states in a static field gradient have been proposed and successfully implemented with high fidelity [17, 35, 37–39]. TīmeklisIn is found that, in the absence of decoherence, the generated particle-field and two trapped-particles entanglement can be enhanced by increasing the Lamb-Dicke parameter. The Lamb-Dicke nonlinearity effect on the generated stationary entanglement, the sudden death and sudden birth of the entanglement, and the …
